Battery Types

Deep Cycle Flooded (Lead Acid)

If you’re okay with a bit of maintenance and want a proven, cost-effective solution, this is for you.

  • What It Is: Traditional, oldest type of rechargeable battery. Uses liquid acid.
  • Good For: General use, reliable, tried-and-true.
  • Drawbacks: Needs regular maintenance (adding distilled water), not great for high-vibration or tilt-prone environments, can spill acid if tipped.

Deep Cycle AGM (Absorbent Glass Mat)

Want a maintenance-free upgrade from traditional lead-acid batteries? AGM is the way to go.

  • What It Is: Lead-acid battery, but the acid is absorbed into glass mats.
  • Good For: Better vibration resistance, longer life, and no maintenance compared to flooded.
  • Drawbacks: More expensive than flooded, can be sensitive to overcharging.

Deep Cycle Lithium

If you’re looking for top-of-the-line, long-lasting performance and don’t mind paying more upfront, go with lithium.

  • What It Is: Uses lithium-ion technology.
  • Good For: Lightweight, high energy density, very long life, zero maintenance.
  • Drawbacks: Expensive upfront cost.

Gel Batteries

Need a battery that can handle awkward positions and tougher environments? Gel is a solid choice.

  • What It Is: Lead-acid battery where the acid is turned into a gel.
  • Good For: No spillage, better for odd positions, some maintenance-free aspects.
  • Drawbacks: More sensitive to high temperatures and overcharging, generally more expensive than flooded.

SMF Batteries (Sealed Maintenance Free)

Need a hassle-free, maintenance-free option for general use? SMF has you covered.

  • What It Is: Usually a lead-acid battery that is sealed and doesn’t require maintenance like topping up water.
  • Good For: No maintenance, simple to use, commonly found in cars and small appliances.
  • Drawbacks: Generally not designed for deep cycling (draining and recharging repeatedly), more of a ‘set it and forget it’ option.
